Farklı yüzey işlemlerinin turkom-cera tam seramiklerin bağlantı direnci üzerine etkisi

Objectives: The purpose of this study was toinvestigate the effect of different surface treatmentson shear bond strength between PanaviaF 2.0 andTurkom-Cera.Materials and Methods: All ceramic, 10x10x2mm sized, 40 Turkom-Cera specimens wereprepared. These specimens were randomly assignedto 5 groups (n=8) according to different surfacetreatments untreated or control (group C),sandblasted (group SB) Rocatec applied (group R)hydrofluoric acid-etched (group HF), and Z Primerapplied (group Z). The resin cement blocks with 2mm height and 8 mm diameter were prepared withPanavia F2.0 from teflon mould. Then they werecemented to Turkom-Cera full ceramic specimens.The prepared specimens were kept in water in roomtemperature for 1week and then shear bond strengthtest was performed at 0,5 mm/min crosshead speedwith universal test machine. One way ANOVA andTukey post-hoc tests were performed for statisticalanalysis.Results: Groups SB and R showed statisticallysignificant higher bond strengths than other groups(p<0.001), but the difference between them was notstatistically significant. (p>0.05). Furthermore, thebond strength difference between groups C, HF andZ were not statistically significant (p>0.05).

ÖZET

Amaç: Bu çalışmanın amacı, farklı yüzey işlemlerinin alumina içerikli Turkom-Cera tam seramik materyalinin Panavia F 2.0 rezin simanla makaslama bağlantı direnci üzerine etkisinin araştırılmasıdır.

Gereç ve Yöntem: Boyutları 10x10x2 mm olan toplam 40 adet Turkom-Cera tam seramik örnekler hazırlandı. Farklı yüzey hazırlıklarına tabi tutulmak üzere örnekler rastgele 8’erli 5 gruba ayrıldı; hiçbir yüzey işleminin uygulanmadığı kontrol grubu (grup C), kumlama grubu (grup SB), Rocatec uygulanan grup (grup R), hidroflorik asitle pürüzlendirilen grup (grup HF) ve Z Primer uygulanan grup (grup Z).Yüksekliği 2 mm ve çapı 8 mm olan rezin siman bloklar Panavia F 2.0 rezin simandan teflon kalıp ile üretildi ve Turkom-Cera tam seramik örneklere simante edildi. Hazırlanan örnekler 1 hafta süreyle oda sıcaklığındaki suda bekletildi ve universal test cihazında 0,5 mm/dak hızla makaslama testine tabi tutuldu. İstatistiksel değerlendirme tek yönlü varyans analizi ve Tukey çoklu karşılaştırma testi ile yapıldı.

Bulgular: Grup SB ve grup R istatistiksel olarak diğer gruplara göre anlamlı derecede yüksek bağlantı dayanımı gösterirken (p<0,001) kendi aralarındaki farklılık anlamlı olarak bulunmadı (p>0,05). Grup C, grup HF ve grup Z arasındaki makaslama bağlanma dayanımı farklılığı istatistiksel olarak anlamlı bulunmadı (p>0,05).

Sonuçlar: Turkom-Cera tam seramiklerin adeziv simantasyonunda 50 µm’luk Al₂O₃ kumlama ve silika kaplama bağlanma dayanımı açısından yeterli ve tatmin edici sonuçlar vermektedir.
